Sterile filtration devices are used to clarify and prevent microbial contamination of cell culture media, cell culture reagents, buffers, biological samples, proteinaceous samples, and more. These devices provide an alternative to autoclaving, which can degrade sensitive, heat-labile biological components. We provide small to large volume Millipore® sterile filters for cell culture, preparation of reagents for long term storage, and other applications.

Compatible with 50 mL centrifuge tubes, Steriflip® filters eliminate the liquid transfer step by integrating directly into the sample tube. To filter, attach the unit to the 50 mL centrifuge tube containing your sample, flip, and apply vacuum. The filtrate collects directly into the attached 50 mL tube. Three membranes are available:
When reliable sterile filtration of media and buffers is critical, laboratories around the world rely on Stericup® devices. A full range of filter membrane materials, pore sizes, and filtration volumes have made Stericup® filters the leader in filtration for cell culture and other applications where sterility is critical. The next-generation Stericup® Quick Release vacuum filtration devices feature ergonomic design innovations that enhance usability and streamline filtration, while safeguarding vital cell cultures with the dependable performance of Millipore® membranes.
Our commitment to sustainability inspired us to design a filter device that helps labs to go green, without compromising sterility. Stericup® E and Steritop® E filters attach directly to commercial media bottles, eliminating the plastic filter funnel to reduce plastic waste up to 48%, with a corresponding significant reduction in packaging, transportation, and storage impacts.
Filter-sterilize volumes up to 2,000 mL using Sterivex™ pressure-driven filter units. With three membrane options and a variety of outlet connections, Sterivex™ filters can fit nearly any workflow and dispense into nearly virtually any storage container. Sterivex™ filters work with peristaltic pumps, syringes, or pressure vessels to eliminate the risk of contamination from decanting or pipetting.
The Stericap™ Universal Bottle-Top Filter Device enables fast vacuum filtration into compatible bottles. Even viscous solutions filter efficiently with no clogging, so these filters are well-suited for serum-supplemented media. Stericap™ filter devices are compatible with vacuum-rated bottles or other receptacles with an inner neck diameter of 20 to 67 mm, providing maximum versatility, capacity, and filtration rate.
Steripak™ filter units are designed for larger-scale pressure-driven filtration of tissue culture media with or without serum supplement. These filters are designed for single use and are not autoclavable. Steripak™ units are available in two maximum volumes to filter up to 10 L or 20 L of fluid. Both sizes are equipped with the low protein-binding, fast flow 0.22 µm pore Millipore Express® membranes. Units are supplied sterile and ready to connect to a pump or pressure vessel.
